Floating Ball Valve End Entry Integral Body (DBB)

Floating Ball Valve End Entry Integral Body (DBB)

Model no. VD1

Valves suitable for Oil & Gas production, processing, transportation, distribution, chemical and petrochemical refining including system isolation, pressure level and flow measurement, instrument drain, chemical injection and sampling for smaller sizes.

 

Floating Ball Valve End Entry Integral Body

 

GENERAL CONSTRUCTION
 

Floating ball valves have the obturator free from axial constraints and it is supported between two soft seat inserts; under pressure the ball compresses the downstream soft insert to obtain the sealing; these valves are generally recommended for use in clean service with limited sizes and ratings. Erreesse production range offers a wide selection of models and construction suitable for critical services also. Erreesse modular double block & bleed (DBB) valves are engineered and manufactured to provide a compact and reliable alternative to multiple instrument valve systems, reducing leak paths and saving installations and maintenance costs.

 

MATERIALS OF CONSTRUCTION
  • Low Temperature and Low Alloy Carbon Steel
  • Stainless steel, Duplex and Super Duplex
  • Nickel alloys
  • Titanium
